YARN CARRIER Filed Nov. 4, 1948 Patented July 1 7, 1951 UNITED STATES PATENT OFFICE YARN CARRIER Edward Jentsch, Clifton, N. J.

Application November 4, 1948, Serial No. 58,266

7 Claims.

The present invention relates to a yarn carrier and relates more particularly to a yarn carrier having parts that are replaceable and adjustable.

, An object of my invention is to provide a yarn carrier in which various parts that are subject to wear or may be damaged may be replaced without discarding the entire carrier. Another object of my invention is to provide a yarn carrier that may easily be adjusted for proper operation in relation to a knitting machine after any part of the carrier has been replaced. Further objects and advantages of my invention will be apparent and best understood from the following description and the accompanyin drawings in which:

' Fig. l'is a perspective view of a yarn carrier embodying my invention;

Fig. 2 is a front view of the yarn carrier illustrated in Fig. 1;

Fig. 3 is a side view of the yarn carrier illustrated in Fig. 1;

Fig. 4 is a rear view of the yarn carrier illustrated in Fig. l; and

Fig. 5 is a side view of part of the yarn carrier illustrated in Fig. 1.

Referring now to the drawings in detail, there is a yarn carrier designated generally by the numeral I. The carrier I includes a main body portion 2 in the form of an angle member. A nose or tube holding portion 3 is adjustably supported at the lower end of the main body member 2 and may be adjusted lengthwise of the main body member 2 so that its end may be readily located at a desired position relative to a knitting machine.

The top of the main body member 2 is T- shaped and has slotted openings 4 in the arms of the T to receive studs 5 that secure the carrier to the knitting machine. A thread guide 6 of wear resisting material, such as hardened steel, is removably supported at the top of the T- shaped portion of the main body portion 2 by a plate I. The plate I isalso held in place by the studs 5 and the center portion of the plate I may be raised to receive the end of the guide 6 between the plate I and the top of the main body portion 2. The end of the guide 6 may be bent as indicated at 8 in Fig. 5 to provide a sprin action that removably holds the guide 6 in place and provides a spring action so that the guide 6 can serve as a washer to hold the studs 5 against loosening.

The lower portion of the main body 2 of the carrier extends downwardly at an angle to the T-shaped top portion and this downwardly extending portion may be arched or curved. The lower end of the downwardly extending portion of the main body 2 is slotted as indicated at 9- and a fastening device or bolt I0 extends through the slot 9. The bolt I0 is threaded to the nose or tube holdin member 3 and the head of the bolt I0 engages with a clamping member I I with the nose portion 3 and the clamping member II bein located on opposite sides of the main body 2.

The main body 2 has recessed portions on its underside'that extend around the slot 9 and these recessed portions are shaped to fit the upper end of the nose portion 3 with a sliding fit so as to hold the nose portion 3 in proper alignment with the main body of the carrier. In addition the clamping member or bracket I I may also be provided with lips Ila that extend overand engage with the side edges of the main body portion 2 of the carrier so that the clamping bracket 1| will not turn when it is tightened. Thus, when the bolt I I] is tightened the nose portion 3 of the carrier is secured in proper alignment to the main body portion 2 of the carrier. When the bolt I0 is loosened, the nose portion 3 may be moved lengthwise of the main body portion 2 without disturbing its alignment in the carrier so as to adjust the position of the end of the nose portion 3 relative to the knitting machine or the nose portion 3 may be removed entirely from the carrier so that it may be re-..

placed. 1

The nose or tube holding member 3 extends downwardly from the main body 2 of the carrier and it may be of the construction in which a pair of opposed spring-jaws I2 and I3 are located at the lower end thereof and engage with and hold a thread-guide tube I4 in place between them. The jaws I2 and I3 may also have apertures I5 and I6 to receive a carrier-tube releaser (not shown) for releasing the tube I4 from the jaws. Such a construction is more fully described and shown in my copending application, Serial No. 58,265 filed November 4, 1948, and reference may be made thereto in regard to such details.

In operation, a thread H, as shown in Figs. 2-4, passes through an opening I8 in the removable thread guide 6- and then through an opening 19 in the main body portion of the carrier. The thread II then runs along the underside of the carrier and over a roller 20 team opening 2I in the tube holder 3. From the opening 2|, the thread I! passes through a groove 22 to the top of the tube I4 and then through the tube I4;

The roller 20 over which the thread' [1 passes on the'back of the main body 2 of the carrier is of hardened steel or other suitable wear resistant material and it contacts with and supports the thread H in a position spaced from the main body of the carrier so that the frictional drag on the thread is reduced to a minimum. The guide roller 20 may be removably supported on the main body 2 of the carrier by a wire clip 23 that is held in place on the carrier by a screw 24. Thus, the roller 20 may be removed and replaced readily if it becomes worn or damaged.

will beseen from the drawings, the thread h 2 1K??? hre R m and the frictional drag on the thread is thus reduced so that the thread may be guided more easily and accurately by the carrier and with reduced breakage. In addition, wear on the can-t rier itself is reduced by the removable guides of wear resistant material and the life of the car rier is greatly increased. In addition, other per-u. tions of the carrier are adjustable and maybe replaced without discarding th entire carrier, if they become worn or damaged.
